The various embodiments of the present invention (individually and in combination) may advantageously help to provide an article with improved fit, absorbency, and leak resistance. The article can also be manufactured at a lower cost and with greater efficiency. In particular, the stretchable attachment of the absorbent composite to the body molding may allow the volume of the absorbent composite to increase during use while being narrow and consistent The fit of the body molding around the waist and torso of the user's body is maintained. Additionally, the body molding can better provide an effective barrier between the wetted absorbent composite and the skin of the wearer. Where leg elastics and inserted portions of the stretchable fastening portions are provided at the lateral side edges of the absorbent composite in the intermediate crotch part edges of the absorbent composite in the intermediate crotch portion of the diaper, these elastic and stretchable side edges may allow the absorbent composite to move outward in volume from the wearer increases without substantially affecting the positioning and snug fit of the leg elastics around the wearer's legs. As a result, the article of the invention can advantageously provide improved absorbency with reduced leakage.

As representatively shown, the front waistband section has 14 the diaper 10 a laterally opposed, front pair of side edge portions 88 , wherein the rear waistband section 12 a laterally opposite, rear pair of side edge areas 86 Has. The intermediate section 16 connects the front and rear waistband sections and provides a crotch area of the diaper, which is typically located between the legs of the wearer. The article may have an inserted mounting receiving zone 50 have, which is arranged on the outwardly facing surface of the article. The acquisition zone may be with a component such as the underlayer layer 30 or the second body molding 53 be formed integrally. As in 2 is shown representative, the receiving zone 50 alternatively, it may be a separately provided element, for example, on the outwardly facing surface of the under-sheet layer 30 is arranged. The liquid-permeable top sheet layer 28 is in facing relationship over the underlayer 30 arranged, wherein the inserted retaining part 48 the absorbent structure between the underlayer layer 30 and the top sheet layer 28 is operatively connected and attached. In special arrangements, the top sheet layer 28 and the retention part 48 be constructed so that they are substantially non-elastomeric and can be operatively attached to the lower leaf element 30 be attached to substantially restrict excessive stretching of the lower sheet member.

1 and 2 show typical plan views of the representative disposable diaper 10 in their generally expanded, uncontracted state (ie, any elastic, induced tightening and contracting is substantially removed), wherein 1 the body-side surface of the diaper, which is to come into contact with the wearer, facing the viewer. The outer edges of the diapers define a periphery with laterally opposed, longitudinally extending side edge edges 20 , and longitudinally opposed, laterally extending end edge edges 22 , The side edges define the leg openings for the diaper and are optionally curved and contoured. The front edges are straight, but may be curved.

With Reference to the designated surfaces of the article and components So are the different inward facing surfaces designed that to the body of the carrier facing, when the article is arranged around the carrier around. The different outward directed surfaces are designed so that they are remote from the body of the wearer when the Article about the wearer is arranged around.

The diaper 10 typically has a porous, substantially liquid pervious topsheet 28 , a substantially liquid-impermeable bottom sheet 30 , a restraint part 48 , which is arranged and connected between the top sheet and the bottom sheet, an outflow control part 46 which is operatively adjacent to the retaining member, and a system of elastomeric, gathering elements such as a system, the leg elastics 34 and waistband elastics 42 having. The outflow control part 46 is in fluid communication with at least one facing major surface of the retaining member 48 arranged, with the top sheet 28 , the bottom sheet 30 , the retaining part 48 , the outflow regulation part 46 and the elastic elements 34 and 42 can be assembled in a variety of well-known diaper designs. The diaper may additionally include a system of containment brims (not shown) and a system of side moldings or tab area elements 38 which can be elastically or otherwise made elastomeric.

Examples of articles that have elastic side moldings and selectively designed Fastening strips and various methods for forming the desired Fastening systems are disclosed in U.S. Patent No. 5,399,219 by T. Roessler et al entitled METHOD FOR MAKING A FASTENING SYSTEM FOR A DYNAMIC FITTING DIAPER and issued on March 21, 1995 (Attorneys directory No. 11 186); in US Patent No. 5,540,796 to D. Fries, entitled A PROCESS FOR ASSEMBLY ELASTICIZED EAR PORTIONS and in the US Patent No. 5,595,618 to D. Fries entitled AN ASSEMBLY PROCESS FOR A LAMINATED TAPE is described.

The diaper 10 generally defines the longitudinally extending length dimension 26 and the laterally-extending width dimension 24 , as in 1 is shown representative. The diaper may have any desired shape such as a rectangular, I-shaped, a general hourglass shape, or a T-shape. In the T-shape, the crossbar of the "T" may include the front waistband portion of the Winrdel or alternatively the rear waistband portion of the diaper.

The Oberblatt 28 and the bottom sheet 30 can generally be coextensive and optionally not coextensive. One or both, the Oberblatt 28 and the bottom sheet 30 can have length and width dimensions that are generally greater than the corresponding dimensions of the retaining member 48 and extend beyond to end edge edges or areas 78 and 79 and side edge margins or areas 80 of the absorbent composite 32 provide. In particular embodiments, the side edge edges of the absorbent composite may be configured to cover at least a portion of the side edges 20 of the article. As in 1 and 1A representatively, the side edges of the absorbent composite 32 for example, the article side edges along the intermediate part 16 of the article. The Oberblatt 28 is operative with the lower leaf 30 connected and arranged over, thereby defining the circumference of the diaper. The waist regions include those portions of the diaper that, when worn, cover or enclose, in whole or in part, the wearer's waist or mid, lower torso. In the representatively shown configurations are the first body molding 52 and the second body molding 53 arranged so that they are the rear or front waistband areas 12 and 14 provide. The intermediate crotch area 16 of the article lies between the waistband areas 14 and 12 and connecting them together and comprising the part of the diaper which, when worn, is positioned between the legs of the wearer and covers the lower torso of the wearer. This is the intermediate step area 16 a region where typically repeated liquid spills occur in the diaper or other disposable absorbent article.

The bottom sheet 30 may typically be along the surface of the outside of the absorbent composite 32 and may be made of a liquid pervious material, but desirably includes a material designed to be substantially impermeable to liquids. For example, a typical bottom sheet may be made from a thin plastic film or other flexible, substantially liquid-impermeable material. The term "flexible" as used in the present specification refers to materials that are compliant and that readily conform to the general shape and contours of the wearer's body. The bottom sheet 30 prevents that in the absorbent composite 32 Excretions contained items such as sheets or outerwear moisten with the diaper 10 get in touch. In specific embodiments of the invention, the bottom sheet 30 For example, a film such as a polyethylene film having a thickness of about 0.012 mm (0.5 mils) to about 0.051 mm (2.0 mils). For example, the under-sheet film may have a thickness of about 0.032 mm (1.25 mils).

Alternative designs of the backsheet may include a woven or nonwoven fibrous fabric layer that is wholly or partially constructed or treated to impart the desired level of liquid impermeability to the selected areas adjacent or immediately adjacent to the absorbent composite. For example, the bottom sheet may be a gas permeable, nonwoven fabric layer that is laminated to a polymeric film layer that may or may not be gas permeable. Other examples of fibrous, cloth-like backsheet materials can comprise a thinned by stretching or wärmegedehntes layer material composed of a 0.015 mm (0.6 mil) thick polypropylene cast film and a 23.8 g / m ² (0.7 ounces per square yard (ounce per square yard - osy)) polypropylene spunbonded material (fibers of 2 denier). A material of this type was used to form the outer shell of a HUGGIES ULTRATRIM diaper which was commercially available from Kimberly-Clark, Corporation. The bottom sheet 30 typically provides the outer shell of the article. Optionally, however, the article may have a separate outer shell component in addition to the lower leaf.

The bottom sheet 30 may comprise a microporous, "breathable" material that allows gases, such as water vapor, from the absorbent composite 32 while essentially preventing liquid precipitates from passing through the bottom sheet. For example, the breathable backsheet may be made of a microporous polymer film or nonwoven fabric that has been coated or otherwise modified to impart a desired level of liquid impermeability. A suitable microporous film may be, for example, a PMP-1 material available from Mitsui Toatsu Chemicals, Inc., a company having offices in Tokyo, Japan; or an XKO-8044 polyolefin film available from 3M Company of Minneapolis, Minnesota. The bottom sheet may also be embossed or otherwise patterned or frosted to have a more aesthetically pleasing appearance sen.

In the various designs of the invention, in which a component such as the lower sheet 30 or the containment brims are designed to be permeable to gas while having a resistance and limited permeability to an aqueous solution, the liquid-resistant component may have a structure that can hold a selected water column of water substantially without passing therethrough leak. A suitable method for determining the resistance of a material to liquid penetration is the Federal Test Method Standard FTMS 191 Method 5514, 1978 method or its equivalent.

The bottom sheet element 30 is sufficiently impermeable to liquid and semi-liquid materials to substantially prevent the unwanted leakage of outgoing materials such as urine and feces. For example, the bottom sheet member desirably may hold a water column of at least about 45 centimeters (cm) substantially without leakage. The lower leaf element 30 may alternatively hold a water column of at least about 55 cm and optionally a water column of at least about 60 cm or more to provide improved benefits.

The size of the sub-sheet 30 is typically determined by the size of the absorbent composite 32 and the special, selected diaper design. The bottom sheet 30 For example, it may have a general T-shape, a general I-shape, or a modified hourglass shape, and may extend beyond the trailing edges of the retaining member 48 at a selected distance, such as a distance in the range of about 1.3 centimeters to 2.5 centimeters (about 0.5 to 1.0 inches), to provide at least a portion of the side and end edges.

The Oberblatt 28 represents a body-facing surface that is compliant, soft-feeling, and non-irritating to the wearer's skin. Furthermore, the top sheet 28 less hydrophilic than the absorbent composite 32 and is sufficiently porous to be liquid permeable, which liquid can easily penetrate its thickness to reach the absorbent composite. A suitable top sheet layer 28 can be made from a wide variety of fabric materials such as porous foams, reticulated foams, apertured plastic films, natural fibers (for example, wood or cotton fibers), synthetic fibers (for example, polyester or polypropylene fibers), or a combination of natural and synthetic fibers. The top sheet layer 38 It is typically used to help isolate the wearer's skin from the fluids contained in the absorbent composite 32 being held.

For the Oberblatt 28 Different woven and non-woven fabrics can be used. For example, the topsheet may be a meltblown or spunbond fabric of the desired fibers, and may also be a composite carded web. The different substances may consist of natural fibers, synthetic fibers or their combination.

For the purpose As used herein, the term "non-woven fabric" means a web of fibrous material. that made without the help of a textile weaving or knitting process becomes. The term "substances" is used to apply to all woven, knitted and non-woven fiber fabrics refer.

The topsheet fabrics may be comprised of a substantially hydrophobic material, where the hydrophobic material may optionally be treated with a surfactant or otherwise to transfer a desired level of wettability and hydrophilic property. In a specific embodiment of the invention, the top sheet 28 a nonwoven polypropylene spunbond web composed of fibers of 2.8-3.2 denier, which are formed at a density of about 0.06 g / cm ³ in a web having a basis weight of about 22 g / m ² and. The fabric may be surface treated with an effective amount of a surfactant such as 0.28% of a Triton X-102 surfactant. The surfactant may be applied by any conventional means such as spraying, printing, brushing or the like.

The Oberblatt 28 and the bottom sheet 30 are interconnected or otherwise joined together in a functional manner. The term "joined together" as used herein includes designs in which the topsheet 28 directly with the bottom sheet 30 by directly attaching the top sheet 28 to the lower sheet 30 , and designs in which the upper sheet 28 indirectly with the bottom sheet 30 by attaching the top sheet 28 is connected to intermediate elements, in turn, on the lower sheet 30 are attached. The Oberblatt 28 and the bottom sheet 30 For example, in at least part of the circumference of the diaper, they may be joined together by attachment mechanisms (not shown), such as adhesive bonds, sonic joints, thermal bonds, attachment, suturing, or any other fastening technique known in the art, and combinations thereof. For example, a uniform, continuous adhesive layer, a patterned adhesive layer, a sprayed-on adhesive pattern, or a patch of separate lines, vertebrae, or dots of construction joints are used to form the top sheet 28 on the lower sheet 30 to fix. It should be readily understood that the attachment mechanisms described above may also be used to interconnect, join, and / or fasten the various other components of the article described herein.

The absorbent body or composite 32 provides an absorbent structure that provides a retention portion 48 for holding and storing adsorbed liquids and other starting material, such as the absorbent pad shown, consisting of selected hydrophilic fibers and highly absorbent particles. The absorbent composite is between the topsheet 28 and the bottom sheet 30 positioned and arranged so that he is the diaper 10 forms. The absorbent composite has a construction that is generally compressible, compliant, non-irritating to the wearer's skin and capable of absorbing and retaining body exudates. It should be understood that for the purposes of the invention, the composite absorbent structure may comprise a single, integral piece of material or, alternatively, a plurality of individual, separate pieces of material operatively joined together.

Various types of wettable hydrophilic fiber material can be used to form the components of an absorbent composite 32 , especially the restraint part 48 , to build. Examples of suitable fibers include naturally occurring organic fibers consisting of inherently wettable material such as cellulosic fibers, synthetic fibers consisting of cellulose or cellulose derivatives such as rayon fibers, inorganic fibers consisting of naturally wettable material such as glass fibers, synthetic fibers consisting of naturally wettable thermoplastic polymers such as special polyester or polyamide fibers, and synthetic fibers consisting of a non-wettable thermoplastic polymer such as polypropylene fibers rendered hydrophilic by suitable means. The fibers may be formed, for example, by treatment with silica, by treatment with a material which has a suitable hydrophilic portion and is not readily removable from the fibers, or by coating the non-wettable hydrophobic fiber with a hydrophilic polymer during or after formation the fibers are rendered hydrophilic. For the purposes of the present invention, it is contemplated that selected mixtures of different types of the above-mentioned fibers may also be used.

Of the Term "hydrophilic" as used herein describes fibers or the surfaces of fibers passing through the aqueous liquids in contact with the fibers are wetted. The degree of wetting of the materials, in turn, may vary the contact angle and the surface tensions the associated fluids and Materials are described. Equipment and procedures used for Measuring the wettability of particular fiber materials or mixtures of Fiber materials are suitable, by a Cahn SFA-222 Surface Force Analyzer system or a substantially equivalent System be provided. If you are using such a system are measured fibers with contact angles smaller than 90 ° as "wettable", while fibers with contact angles greater than 90 ° as "not wettable".

The absorbent composite structure 32 may consist of a retention member having a matrix of hydrophilic fibers, such as a cellulosic tissue web, intermixed with particles of high-absorbency material. In special arrangements, the retaining part 48 of the absorbent composite 32 comprising a blend of superabsorbent hydrogel-forming particles and synthetic polymeric meltblown fibers or a blend of superabsorbent particles with a fiber coform material comprising a blend of natural fibers and / or synthetic polymer fibers. The superabsorbent particles may be substantially homogeneously mixed with the hydrophilic fibers, or they may be mixed nonuniformly. For example, the concentrations of the superabsorbent particles can be arranged in a stepless gradient through a substantial portion of the thickness (z direction) of the absorbent structure at lower concentrations to the body side of the absorbent composite and relatively higher concentrations to the outside of the absorbent structure. Suitable z-slope designs are described in USP 4,699,823 issued October 13, 1987 to Kellenberger et al. Alternatively, for example, the concentrations of the superabsorbent particles can be arranged in a stepless gradient through a substantial portion of the absorbent structure's z-directional absorbent structure having higher concentrations to the body side of the absorbent composite and relatively weaker concentrations to the outside of the absorbent structure. The superabsorbent particles may also be arranged in a generally single layer in the matrix of hydrophilic fibers. In addition, two or more different types of superabsorbents may selectively be present at different locations in or be arranged along the fiber matrix.

The Highly absorbent material can be absorbent, gel-forming materials like superabsorbents include. Absorbing, gel-forming materials can natural, synthetic and modified natural polymers and materials be. additionally can absorbent, gel-forming materials inorganic materials such as silica gels or organic compounds such as crosslinked polymers be. The term "cross networked " any means to substantially water-soluble materials substantially insoluble in water, but swellable close. Such means can for example, a physical web, crystalline areas, covalent bonds, ionic complexes and compounds, hydrophilic Compounds such as hydrogen bonds and hydrophobic compounds like Van der Waals forces exhibit.

synthetic absorbent gelling materials are typically dry gels, the hydrogels form when wetted. However, the term "hydrogel" has become common used to go as well both the wetted and non-wetted forms of the material to call.

As previously mentioned, the highly absorbent material used in the absorbent composite 32 is generally used in the form of individual particles. The particles may be of any desired shape, for example helical or semi-helical, cubic, rod-shaped, multi-faceted, etc. Shapes having a largest dimension / smallest dimension such as needles, flakes, and fibers are also contemplated for use herein. Conglomerates of particles of the absorbent gelling material may be present in the absorbent composite 32 also be used. For the application, particles having an average size of about 20 microns to about 1 millimeter are desired. "Particle size" as used herein means the weighted average of the smallest dimension of each particle.

The hydrophilic fibers and high-absorbency particles can be designed to form an average basis weight of the composite that is in the range of about 400-900 g / m ² . In certain embodiments of the invention, the average basis weight of the composite is in the range of about 500-800 g / m ² , alternatively in the range of about 550-750 g / m ² , to provide the desired utility value.

To improve the inclusion of the highly absorbent material, the absorbent composite structure may be used 32 an outer packaging like a cover sheet 74 have, directly on the retaining part 48 is disposed adjacent and thereabout and can be connected to the absorbent structure and the various other components of the article. The cover sheet is preferably a layer of absorbent material covering the bodyside and outboard major surfaces of the retention member, and preferably enclosing substantially all peripheral edges of the retention member to form a substantially complete sleeve therearound. Alternatively, the cover sheet may provide an absorbent wrap that covers the bodyside and outboard major surfaces of the retention member and encloses substantially only the side edges of the retention member. As a result, both the linear and inwardly curved portions of the side edges of the cover sheet would be closed around the retention member. In such an arrangement, however, the end edges of the cover sheet would not close completely around the end edges of the retainer portion at the waistband portions of the article.

For example, the entire envelope sheet 74 or at least the bodyside layer of the cover sheet comprises a meltblown web composed of meltblown fibers such as meltblown polypropylene fibers. Another example of the absorbent sheath 74 may comprise a low porosity cellulosic tissue such as a cloth made from an approximately 50/50 mixture of hard wood / softwood fibers is made.

The absorbent wrapper 74 may comprise a multiple-element cover sheet having a separate body-side cover layer and a separate outer-side cover layer, each behind all or some of the peripheral edges of the retainer portion 48 extends. Such a design of the cover sheet may include, for example, the formation of a substantially complete seal and the closure of the peripheral edges of the retaining member 48 facilitate. Moreover, in the rear waistband of the illustrated diaper, the absorbent wrapper may be configured to extend an increased distance away from the periphery of the containment member to add opacity and strength to the back side portions of the diaper. In the illustrated embodiment, the bodyside and outboard layers of the absorbent wrap can become 74 extend at least about 13 mm (1/2 inch) beyond the peripheral edges of the retention member to provide an outwardly projecting flange-like connection region over which the perimeter of the bodyside portion of the absorbent cover is completely or partially coextensive with the perimeter of the outboard portion of the absorbent Serving can be connected.

The bodyside and outside layers of the envelope 74 may consist of the substantially same material or of different materials. For example, the outside layer of the cover sheet may be made of a relatively low basis weight material having a relatively high porosity, such as a waterproof cellulose cloth made of softwood pulp. The bodyside layer of the cover sheet may comprise any of the previously described cover sheet materials which have a relatively low porosity. The low porosity bodyside layer can better prevent the migration of superabsorbent particles to the wearer's skin, and the high porosity, low basis weight, outside layer can help reduce costs.

The diaper 10 can also have an outflow control layer 46 which helps to decelerate and disperse the effluents of liquid which may have been introduced into the absorbent composite of the article. The outflow layer 46 In addition, it can temporarily hold the liquid for a limited period of time, spread it and direct the distribution of the liquid and then the liquid for absorption into the retention part 48 release. In the illustrated embodiment, the outflow layer 46 for example, on an inwardly facing, bodyside surface of the topsheet layer 28 are located. Alternatively, the outflow layer 46 adjacent to an outer side surface of the topsheet layer 28 so they are between the top sheet layer 28 and the retention part 48 lies. Examples of suitable outflow control layers 46 are described in U.S. Patent No. 5,486,166 and U.S. Patent No. 5,490,846.

Each body molding may have a desired shape, which may be generally rectangular or not rectangular. Laterally opposite end portions of the body molding may extend across the side edges of the absorbent composite 32 extend to extended flap parts 38 of the article. Accordingly, each body molding may extend over substantially the entire transverse width of its corresponding waistband portion of the article. Each body molding may extend laterally across the side edges of the topsheet layer 28 and laterally across the side edges of the bottom sheet layer 30 extend. In particular arrangements, the body molding may be formed with lateral end portions having a tapered shape to provide tapered tab portions. Each tapered flap portion may have a relatively longer, longitudinal length adjacent the side edges of the absorbent composite and a relatively shorter, longitudinal length at the laterally distal ends of the flap portion.

In desired arrangements, at least one central part 64 the laterally extending and longitudinally inner edge 62 of the first body molding 52 with the bodyside surface of the absorbent composite 32 be essentially unpaved. Similarly, the second body molding 53 a longitudinally inner end edge closure 63 have at least one middle part 65 the front edge 63 with the absorbent composite 32 may be essentially unpaved. If desired, either one or both inner edges may be substantially straight or curved. In particular embodiments, at least a portion of the inner edge of one or both body moldings 52 and 53 be arranged in a configuration which is concave inside, as in 1 is illustrated. As representatively shown, the inserted concave curvature may begin at each side edge of the absorbent composite and may generally laterally traverse the absorbent composite with a mid-portion of the curve offset toward the longitudinal end of the article. The curvature may help to provide improved conformance of the body molding to the contours of the wearer's body.

In further embodiments of the inven The first longitudinal end edge can be used 82 of the substantially entire absorbent composite 32 relatively inward of the longitudinal outer end edge 60 of the first body molding 52 be spaced. Accordingly, the body molding may extend longitudinally behind its corresponding generally adjacent end termination edge 82 of the absorbent composite and projecting lengthwise beyond it. Similarly, the second longitudinal end edge 83 of the substantially entire absorbent composite 32 relatively inward of the longitudinal outer end edge 61 of the second body molding 53 be spaced. Accordingly, the second body molding may extend longitudinally behind its corresponding generally adjacent end termination edge 83 of the absorbent composite and projecting lengthwise beyond it.

During the state of normal use, there may be the stretchable attachment portions 90 advantageously allow and for a controlled expansion of the volume of the absorbent composite 32 especially after the absorbent composite has begun to absorb liquids. In various embodiments of the invention, any stretchable attachment portion 90 may be a separately provided element that is inserted into the article or may be integrally formed from inserted parts of other existing components of the article. For example, the stretchable attachment portion may be made from inserted parts of the lower sheet 30 , of the Oberblatts 28 or their operative combinations are formed. In particular embodiments of the invention, the various stretchable attachment portions may be substantially free of absorbent materials such as hydrophilic fibers and superabsorbent polymers.

Regarding 1A can the stretchable attachment section 90 For example, at least one z-folded pleat part 92 having the z-folded pleat part on each side region 80 of the absorbent composite 32 can be provided. For example, in the representatively shown arrangements, the pleat portion may provide a predetermined array of toothed layers that may be flattened together to provide an initial design for a low volume of the absorbent composite 32 provide. During application, and especially during liquid absorption, the splined layers may operatively move apart to form a substantially continuous series of one or more increasingly volume increasing configurations for coaction with an increasing volume of the absorbent composite, particularly increasing volume of the retaining part 48 to provide.

In particular embodiments, the extendable attachment portion 90 have a z-folded or other separately provided component configured to contain the absorbent composite 32 and the outward facing surface 56 of the first body molding 52 connects with each other, as in 7 is represented representatively. Alternatively, the substantially z-folded pleat part 92 by inserted side edge portions of the top sheet layer 28 and / or the underlayer layer 30 be provided laterally over the terminal side edges of the retaining member 48 extend beyond. As in 6 Representatively, the z-folded pleat member may include side edge portions of both the topsheet layer 28 as well as from the lower sheet layer 30 exhibit. In this example, the edges of both the substantially liquid impermeable bottom sheet 30 as well as the substantially liquid-permeable top sheet 28 laterally behind the closing side edges of the retaining part 48 and the envelope 74 extend and beyond stand out. The combined side edges of the protruding underleaf and topsheet layers may then be z-folded to form the desired, stretchable attachment portion.

As in 6A representatively, the z-folded pleat part may alternatively have side edge portions only from the under-sheet layer 30 exhibit. In this example, the side edges of the substantially liquid-impermeable bottom sheet may become 30 laterally behind the closing side edges of the retaining part 48 and the envelope 74 extend and beyond stand out. The extended margins of the underlayer layer 30 can then be z-folded to form the desired, stretchable attachment portion. Optionally, the top sheet layer 28 also be designed so that it is stretchable laterally.

In various embodiments of the invention, each leg elastics element 34 are attached to the outwardly facing surface of the laterally protruding underlayer layer at its lateral side terminating edge so as to be longitudinally along its associated side edge of the absorbent composite 32 extends. As a result, one of the z-folds folded 92 located in each side edge of the absorbent composite and may substantially run along the full length of the absorbent composite.

The relatively outer edge of each z-shaped fold 92 is operative on its associated body molding 52 or 53 attached at a location located inboard of its corresponding relatively adjacent longitudinally extending side edge of the associated body molding. Accordingly, the by the fold 92 provided expandable attachment portion provide a mechanism that allows the absorbent composite 32 allows itself to stretch outward and away from the body moldings and the wearer's body.

With respect to the substantially z-folded pleat elements 92 The z-folded pleats extend longitudinally along the article length 26 , Desirably, the immediately adjacent panels in the pleats are substantially unsecured with each other. Optionally, a small amount of adhesive or other type of joint may be applied to secure two or more of the adjacent pleat panels together. However, such an attachment between the pleat plates should be designed with a strength and a distribution that the desired extent of the attachment sections 90 not overly handicapped. If the restraint part 48 Absorbs liquid and increases in volume, the resulting expansion of the retaining member exerts a tensile stress on the stretchable mounting portions 90 out. The subsequent expansion of the attachment sections 90 Operatively relieves the applied stresses and increases the volume of the restraint part 48 in a way that allows the retention part to be outward from the first body molding 52 grows away. As a result, the first body molding can 52 maintains its desired fit closely over the body of a wearer and may better resist the formation of crevices or sags that may allow excessive, undesirable leakage.

Other embodiments of the invention may include stretchable attachment portions 90 have in which a laterally stretchable area or element 68 (eg 7 and 8th ) is designed so that it is the absorbent composite 32 and the outward facing surface 56 of the inserted body molding 52 or 53 connects together, if appropriate. In this design, each leg elastics element 34 on an inwardly or outwardly facing surface of its respective extensible element 68 attached to an outer lateral end side edge of the stretchable member, so as to extend in the longitudinal direction of the article. As a result, the leg elastics are 34 not directly on the absorbent composite 32 attached. The stretchable element 68 can be formed from various suitable materials such as woven or non-woven crimped fabrics, crimped sheets, apertured films, knitted fabrics, and the like, and combinations thereof.

In particular embodiments, the extensible element 68 a separately provided component which is inserted and attached to the article as in 7 is represented representatively. Alternatively, the stretchable element 68 integral with or from another, existing component such as the top sheet layer 28 (eg 6B ) or the bottom sheet 30 ( 8B ) be formed. At least a portion of the extensible topsheet or backsheet may extend laterally beyond the termination side edges of the retention member 48 and the envelope 74 extend and beyond.

Regarding 6A For example, the stretchable element may comprise a plurality of micro-folds formed therein 94 to have. As representatively shown, the microfaltened component 94 arranged separately and inserted into the article at a location intermediate between the absorbent composite 32 and the outward facing surface 56 of the first body molding 52 lies. Alternatively, the micro-terminated component 94 by substantially uniform portions of the topsheet layer 28 and / or the underlayer layer 30 be provided in one piece. The unitary sections may extend laterally beyond the termination side edges of the retention member 48 extend and have the desired micro-folds formed therein. The micropleated materials can include woven fabrics, nonwoven fabrics, polymeric films, and the like, and combinations thereof that have been processed to produce the desired micro-folds. Such processing may include, for example, conventional crimping and micro-crimping methods.

In other embodiments, the stretchable attachment portions 90 an elastomeric material, at least along the width of the article 24 is elastically stretchable. The elastomeric material may consist of films, filaments, laminated composites and the like and combinations thereof. An elastomeric material may be stretched to 67% elongation for the purposes of the present specification and then retract. After retraction, the retraction force at 50% extension is at least a minimum of about 40 grams (gmf - grams force) per inch of crosswise length of material (about 16 gmf per cm of crosswise length, about 0) , 15 Newtons per cm of the crosswise length). additionally at 20% elongation, the retractive force is at least 10 gmf per inch of the crosswise length (about 4 gmf per cm of crosswise length, about 0.04 Newton per cm of crosswise length). The crosswise length is measured perpendicular to the direction of the applied tensile force. For a test specimen taken from the illustrative designs, the cross-length of the specimen would generally be along the longitudinal direction of the article 27 lie.

In still other designs, the underlayer layer 30 contain an elastomeric material along the width of the article 24 is elastically stretchable as in 8B is shown representative. Each laterally opposite side area 80 of the absorbent composite 32 may be a corresponding, laterally opposite side region of the lower sheet layer 30 exhibit. Each side region of the under-sheet layer desirably extends laterally beyond its respective terminal side edges of the retaining member 48 out.

In particular embodiments of the invention, any expandable attachment portion 90 a transverse extension (along the lateral direction 25 ) of at least about 1 cm when subjected to an applied lateral pulling force at a load of 30 grams per inch of the criss-cross length of the stretchable attachment portion (about 12 gmf per cm of crosswise length; about 0.12 newton per cm of crosswise length). subject. Alternatively, the stretchable attachment portion 90 provide an extension of at least about 2 cm and optionally an extension of at least about 4 cm with an applied tensile force to provide improved utility. In further embodiments, the stretchable attachment portion 90 provide an extension of no more than about 12 cm with an applied tensile force of 50 gmf per inch of the crosswise length of the stretchable attachment portion (about 20 gmf per cm of crosswise length, about 0.19 newton per cm of crosswise length). Alternatively, the stretchable attachment portion may provide an extension of no more than about 10 cm, and optionally no more than about 8 cm, to provide improved benefits. For the purposes of these extension parameters, the crosswise length of the stretchable attachment portion is measured perpendicular to the applied tensile force. For a test specimen taken from the illustrated designs of the invention, the cross-length of the specimen would generally be along the longitudinal direction of the article 27 lie.

A suitable method of producing a representative tensile versus elongation curve and determining the degree of elongation and / or retractive force parameters of a selected component or material may be determined by ASTM Standard Test Method D882 (Tensile Method for Tensile Properties of Thin Plastic Sheeting) of December 1995 with the following features. The "width" of the test piece will be a crosswise width that is conveniently obtained from the product being tested, and is desirably about 2 inches (about 5.04 cm). The width of the test piece is perpendicular to the direction of the tensile force applied during the test. For example, with regard to the configurations shown, the width of the test piece generally corresponds to the longitudinal dimension of the stretchable attachment portion 90 along the longitudinal direction 27 of the article. The initial distance of the jaws of the tensile tester is 3 inches (7.62 cm), with the movable jaw being moved at a constant speed of 50 mm / min. The movable jaw is stopped at an extension of 50 mm for a period of 10 seconds and then returned to the initial starting position at a speed of 50 mm / min. The Full Strength Retraction Cycle Curve can be recorded on a conventional computer equipped with commercially available software such as TestWorks for Windows, Version 3.09, available from MTS System Corporation, a 14000 Technology company Drive, Eden Prairie, MN. The data obtained are normalized and recorded in respective units of force per unit length such as the load in grams per inch or the load in grams (or Newtons) per centimeter of the "width" of the test piece.

The carrier layer 96 desirably consists of a woven or non-woven fabric having a basis weight in the range of about 10-50 g / m ² , but may optionally consist of a polymeric film material. For example, the illustrated backing layers may be comprised of a non-woven polypropylene spunbonded web, wherein the pair of backing layers are adhesively bonded together with a suitable adhesive pattern, such as a swirl pattern of pressure-sensitive adhesive.

As representatively shown, each of the leg elastics may be 34 operatively on an outwardly facing surface of at least a portion of the lateral side edge edges 20 attached to the article. In the illustrated embodiment, for example, the side edge edges 20 of the article through side edge portions of the absorbent composite 32 provided laterally across the laterally opposite terminal side edges of the retaining member 48 extend beyond. It should be readily appreciated that any of the conventional attachment mechanisms described in the present disclosure may be used to secure the leg elastics into the article.

The elastic members may comprise a single thread of elastic material or various parallel or non-parallel threads 98 made of elastic material or can be applied in a rectilinear or curved arrangement. Where the threads are not parallel, two or more of the threads may overlap or otherwise be joined together in the elastic member. In particular arrangements, the elastic members may comprise elastomeric threads 98 optionally, between the top sheet layer 28 and the underlayer layer 30 of the absorbent composite 32 are located and laminated. The elastic band elements can be attached to the diaper in any of various ways attached, which are known in the art. For example, the elastic members may be ultrasonically bonded, heat and pressure sealed by a variety of bonding patterns, or sprayed or swirled patterns of a hot melt adhesive with the diaper 10 liable to be connected.

Where the leg elastic elements 34 a backing sheet to which is attached a group of elastics composed of a plurality of individual elastic threads, the elastic threads may overlap or be joined together or be completely separated and spaced from each other. The carrier sheet may comprise, for example, a 0.002 cm thick polymer film, such as a polypropylene embossed polypropylene film. For example, the elastic yarns may be made of LYCRA elastomer available from DuPont, a business having offices in Wilmington, Delaware. Each elastic thread is typically in the range of about 470-1500 decitex (dtx) and may be about 940-1050 dtx. For example, in specific embodiments of the invention, three or four threads may be used for each elastic leg bandage.

In addition, the leg elastics can 34 generally straight or optionally curved. For example, the curved elastics may be bent inwardly toward the diaper's longitudinal centerline. In particular embodiments, the curvature of the elastics need not be symmetrically designed or arranged relative to the lateral centerline of the diaper. The curved elastics may have an inwardly and outwardly curled type of curvature, the length of the elastics being selectively offset at a selected distance from the either front or back waistband of the diaper to provide the desired fit and look , In particular embodiments of the invention, the innermost point (vertex) of the group of curved elastics may be offset from the front or back waistband of the diaper, whereby the outwardly bent portion may be positioned toward the front waistband of the diaper.

As representatively shown, the diaper can 10 a waistband 42 have, in the longitudinal edges of one or both, the front waistband 14 and the rear waistband 12 , is arranged. The waistband rubbers may be made of any suitable elastomeric material such as an elastomeric film, an elastic foam, a plurality of elastic threads, an elastomeric fabric or the like. Suitable elastic waistband constructions are described, for example, in US Pat. No. 4,916,005 to Lippert et al.

With reference to the representative designs according to 1 and 2 The article can be a system of "tabs" areas or tab elements 38 exhibit. In special arrangements, each tab region or flap element extends 38 laterally at the opposite lateral ends of at least one waistband part of the lower sheet 30 as the representatively illustrated rear waistband part 12 to provide a completion page section for the article.

In addition, each tab portion may essentially be of a laterally extending end collar edge 76 tension to approximately the location of its associated and corresponding leg opening portion of the diaper. The diaper 10 for example, has a laterally opposed pair of leg openings passing through the curved edges of the tab portions in conjunction with the corresponding adjacent central portions of the shown pair of longitudinally extending side edge portions 20 (eg 1 ) provided. In alternative configurations, these tab portions may be provided by a system of separately provided tab members (not shown).

In the various configurations of the invention, the tab portions may be integrally formed with a selected diaper component. For example, the tab areas 38 from the material layer, which is the underlayer layer 30 or from the material used to make the top sheet 28 to be provided, integrally formed. In alternative designs, the tab areas 38 provided by one or more separately provided elements, which are associated with the sub-sheet 30 , with the top sheet 28 , are connected and joined together between the bottom sheet and the top sheet or in various fixed combinations of such compositions.

In particular embodiments of the invention, each of the tab portions 38 be formed from a separately provided piece of material that is then assembled and fastened fittingly with the selected front and / or rear waistband part of the diaper article. For example, each tab area 38 at the rear waistband part of the bottom sheet 30 may be attached along the attachment zone of the tab region and may be operatively attached to either or both of the underleaf and topsheet components of the article. The interior region of the attachment zone of each tab region may overlap and laminate with its corresponding side leading edge region of the waistband portion of the article be. The tab portions extend laterally to form a pair of opposing waistband portions of the diaper and are secured by suitable coupling means such as adhesive bonding, thermal bonding, ultrasonic bonding, clamping, stapling, stitching and the like. Desirably, the tab portions extend laterally beyond the terminal side edges of the bottom sheet layer and the topsheet layer at the corresponding, secured waistband portion of the article.

The tab areas 38 may consist of a substantially non-elastomeric material such as polymeric films, woven fabrics, non-woven fabrics or the like and combinations thereof.
